DEVICE FOR COILING-METAL RODS.4

lSPECIFICATION forming part of Letters Patent No. 412,565, dated October8, 1889.

Application led July 8, 1889. Serial No. 316,793. (No model.) l

.To @ZZ whom it may concern:

Be it known that I, FRANK G. TALLMAN, a citizen of the United States,residing at Beaver Falls, in the county of Beaver and State ofPennsylvania, have invented new and useful Improvements in Devices forCoiling Metal Rods; and I do hereby declare the following to be a full,clear, and exact description of said invention, reference being had tothe accompanying drawings, and to the letters or gures of referencemarked thereon, which form a part of this specification.

My invention relates to improvements in devicesfor coiling metal rods asthey emerge from the rolls.

In applications filed by me March 5, 1889, SerialNos. 301,908 and301,909, I have claimed the method of and apparatus for coiling metalrods as they emerge from the rolls, said method and apparatusconsisting, broadly, in passing the rods on their emergence from therolls through a bent rotating guide-tube, which forms the rods intoloops or spirals, and in then arresting said loops on a suitablestandard in the -form of coils. v

This invention is designed as an improvement on the mechanism shown anddescribed in the applications above referred to.

The points of improvements will be fully described, and specificallypointed out in the claims.

Referring to the drawings, Figure 1 is a top or plan view of my device.Fig. 2 is a side elevation of my device, and also the rotating tube,which guides the rods and causes them to assume a spiral form. Fig. 3lis a top or plan View of another form of device for turning the catcheror carrier around in a horizontal plane, so as to draw the rear end ofthe rod from the guide-tube. Fig. 4. is a side view of the device shownin Fig. 3, mounted on an endless carrier. Fig. 5 is a top or plan viewof the catcher adapted to be turned around by hand. Fig. 6 is a top orplan view of the catchers or carriers arranged to be turned by hand in ahorizontal plane. Fig. 7 is a side view of the devices shown in Fig. 6.

A indicates the side frames of the machine, in the top of which ismounted in suitable bearings the shaft B.

C C are catchers or standards secured to the shaft B and adapted torotate with it, said catchers or standards being designed to receive thecoils of wire as they are formed andV lthrown from the revolvingguide-tube D. I have found in practice that when the rear end of the rodhas emerged from the -rolls the power of the rolls which has heretoforebeen `exerted to force the rod through the guidetube D ceases,.and thata few feet of the rod `remains in the guide-tube, and it is with a `Viewto Withdraw this end from the guidetube that I have devised thefollowing.

E is a metal or other suitable frame, which is also secured to the shaftB and adapted to rotate with it, said frame being provided at each endand on opposite sides with toothed or serrated bars F, the office orfunction of which is to pull or assist in pulling the rear end of therod out of the guide-tube. In this connection it "may be proper to statethat the serrated back a of the standard C also serves to pull the endof the rods of the guide-tube when the coil has been wound thereon andthe standards caused to partially rotate with the shaft B. y

Gr is a disk rigidly secured on the shaft B, said disk being providedwith holes b b, to receive a pin or bolt H, which holds the catchers orstandards C and frame E rigidlyT in position while the rods are beingcoiled onto the f catchers. The other end of the pin or bolt H is bentto forni a right angle and is rigidly secured to the shaft I, which ismounted in the frame A, said shaft being connected to the foot-lever Kby means of the bar L, and by means of which the bolt or pin H isdisengaged from the hole b and then allowed to make a half-revolution. Asuitable spring may be used to force the bolt forward into engagementwith the holesh to stop the catchers or standards in their properposition. For example, when a rod is coiled on the top catcher orstandard the attendant steps on the foot-lever K, thereby disengagingthe pin orbolt from the hole in the disk G. He then pulls down on theend of the table or frame F. at M until the weight of the descendingcoil is sufficient to pull the catcher over into the reversed position,when the coil will remain suspended on the horn of the catcher, as shownat N, Fig. 2, until it is removed. When this large mass of metal is inmotion, it is more or less difficult to stop it, and it vjars the IOOmachinery and brings quite a heavy strain on the pin or bolt H. Toobviate this I have arranged a spring O, so it will come in contact withone end of the frame E, acting as a `brake to retard the motion of theframe.

have assumed an oval or horse-collar shape.

This makes the bundles look badly, and to obviate it I have the coil asit tips over to rest on the plate R, supported on the frames A. The hotbundle or coil while resting on the plate will assume an oval form withits longest axis horizontal. Then the weight of the coil while beingcarried away on the hook counteracts this oval shape, so that thebundles or coils will be practically round by the time they are carriedto the place of deposit.

In Figs. 8, 4, 5, 6, and 7 Ihave shown other means of operating thestandards or catchers in order to pull the rear end of the rod from theguide-tube, and instead of turning the catchers or standards inavertical plane, as shown in Figs. l and 2, I turn them around in ahorizontal plane.

In Figs. 3 and 4 the catchers are mounted on an endless traveling beltS. The base of the catchers or standards are provided with teeth whichengage the teeth of the stationary rack-bar T, secured to the frame ofthe machine, which imparts to the catchers a horizontal rotary motionafter the rod has been coiled thereon, so as to draw the rear y end ofthe rod from the guide-tube and Wind it in with the coil or bundle, andafter having become disengaged from the rack-bar the catcher is carriedaround by the endless belt and the coil or bundle taken therefrom, it

being understood that several of the catchers or standards are arrangedon the endless carrier S.

In Fig. 5 I have shown a single catcher or standard adapted to berotated to draw the rear end of the rod from the guide-tube. In thisinstance the catcher is rotated in a horizontal plane by means of thespur-gear V, meshing with the annular gear W of the catcher, saidspur-gear being operated by the crank-arm A', and in Figs. 6 and 7 thesame devices are employed as adapted to a horizontal turn-table, onwhich are mounted two or more lcatchers or standards.

What I claim, and desire to secure by Letters Patent, is.-

l. In a device for coiling metal rods a they emerge from the rolls, thehorn-shaped revoluble catchers or holders, provided with a serratedback, in combination with a revoluble frame for drawing the rear end ofthe rod from the guide-tube, as set fort-h.

2. In a device for coiling metal rods as they emerge from the rolls, thecatchers or standards C, and frame E, mounted on asuitable shaft, incombination with the disk, bolt, bar, and treadle, as set forth.

3. In a device for coiling metal rods as 4they emerge from the rolls,the frame, and catchers or standards revolubly mounted in the supportsA, and a spring-brake adapted to inipinge against the end of the frameto arrest its motion, as set forth.

4. In a device for coiling metal rods as they emerge from the rolls, thehorn-shaped standards or catchers C C, mounted on a central axis andadapted to be rotated around the same, in combination with the restingor stop plate.

In testimony whereof I aix my signature in the presence of twosubscribing witnesses.
